Setup Guide for Beginners

Tyres

Current Setup / TAB Tires

Pressure

For GT3, Cup and ST cars the tyre pressure between 27.0 and 28.0 PSI is optimal while racing in dry conditions. For wet it is between 30 and 31 PSI. For GT4 cars the tyre pressure between 26.5 and 27.0 PSI is optimal while racing in dry conditions.

What should you think of:

1. Get tyre pressures in the range between 27 - 28 PSI resp. 26.5 - 27 PSI for GT4 cars.
2. Use IMO tyre temperatures for tweaking of camber and toe settings
3. If for whatever reason your tyre temperatures aren't in the operation window, use brake duct settings, since heat from the brakes also effects tyre temperatures

Toe

Angle of the wheels, looking from above. You should only have toe out in the front.

In	Out

Camber

Camber enables more tyre surface area to touch the track, giving more grip, countering leaning of the car while turning. You should only have negative camber.

Neutral	Negative	Positive

Check IMO Readings to set camber angle.

Negative	Positive

Caster

Caster angle impacts the stability of the car and how heavy the steering feels. It also causes car to steer to self center. For Sim Racers, not to much important, because of FFB settings, best to leave it at stock angle.

Neutral	Negative	Positive

Solutions to Handling Issues

Braking

Loss of Control
1. Move brake bias forward 2. Decrease slow damper

Front Tyres often lock
Move brake bias backward

Car pitches to much
Stiffen front springs

Nose hits floor
1. Increase ride height 2. Adjust bump stops 3. Stiffen front springs

Excessive locking
Reduce overall brake pressure (use with caution)

Turn in

Understeer
All Speeds: 1. Adjust front tyre pressures 2. Soften front anti-roll bar 3. Increase front toe out 4. Decrease diff coast locking 5. Soften front springs Mid-High Speed: Reduce rear wing angle or Increase front wing angle When braking: Move brake bias backward

Oversteer
All Speeds: 1. Adjust rear tyre pressure 2. Stiffen front anti-roll bar 3. Decrease front toe out 4. Stiffen diff coast locking 5. Soften front springs Mid-High Speed: Increase rear wing angle or Decrease front wing angle

Lift off oversteer
1. Increase diff coast locking 2. Increase pre-load value

Corner Exit

Understeer
All Speeds: 1. Stiffen rear anti-roll bar 2. Increase diff power locking 3. Stiffen rear springs Mid-High Speed: Reduce rear wing angle or increase front wing angle

Oversteer
All Speeds: 1. Soften rear anti-roll bar 2. Decrease diff power locking 3. Soften rear springs Mid-High Speed: Increase rear wing angle or decrease front wing angle

Lift off oversteer
PICNIC (Problem in chair, not in car)

Car bounces during weight transfer
When Braking, Accelerating & Turning Increase slow damper settings On Bumps / Curbs Increase fast damper settings

Other

Tyres overheat
All Over: 1. Increase pressures 2. Decrease toe value On Inside Edge Reduce negative camber On Outer Edge Increase negative camber In Middle Reduce pressures

Tyres cold
All Over: 1. Decrease pressures 2. Increase toe value

Car edgy during weight transfar
When Braking, Accelerating & Turning Decrease slow damper setting On Bumps / Curbs Decrease fast damper setting

Low top speed
Reduce wing values

Car edgy during weight transfar
When Braking, Accelerating & Turning Decrease slow damper setting On Bumps / Curbs Decrease fast damper setting

Tips

Ride height
As low as possible, but avoid grounding car or stalling the aero

Dampers
Bump setting should be lower than the corresponding rebound setting Try to use the lowest setting that avoids oscillation / bouncing Can be used to tune the responsiveness of the car. High values = more responsive Low values = more stable

Aero
Use ride height and rake to generate as much downforce as possible, then trim the aero balance using the wings and / or splitter. Increasing the rake moves the aero balance backwards. Run the car as stiff as needed to maintain stable ride height

Brake bias
Front tyres should lock just before the rears for best stability
